I'm definitely guilty of preaching as you say. The entire reason for my rants and endless babbling is to try to show people, at least through my understanding, how many of the "facts" you say they accept through faith are not so cut and dry. Or so to speak to spit out the other coloured kool aid. I know people will disagree with that, and I'm really quite fine with that.
Do you want to really know what irks me about this? No matter if you follow this or that or the other lines out there, inside we all know what we are doing isn't right. Many of the people I've discussed this topic with have made changes in their behaviour, even if they don't agree with the human factor in climate change. You don't need any explanations from a Ph.D to tell you that using cleaner fuels is a good thing. You don't need Al Gore to tell you that for every action we perform there are reverberating reactions, consequences if you will. No one in their right mind believes we should pollute ad nauseum, willy nilly without a care in the world. Common sense is more valuable than 1000 papers pointing fingers. Common sense is better than drinking that kool aid.
What I'd really like to dive into is what pre-dispositions are brought into this mess. That's really what it is now, a great big mess. The message is polluted with political affiliations and it's polluted by fear mongering on both sides. Perhaps what is worst of all is our attention is being swallowed by the messengers who are framing the whole issue and cheapening the very wholistic notion that we've lost along the way. Being 'left' or 'right' shouldn't be a determinant in how we view the issue, but that time has long since past. I don't know how we can get back to that point, where we can all objectively evaluate where we are, what we are doing and why we have this preponderance to camp on the issues which really have nothing to do with the bigger picture.
I was pondering this just now on the walk back from the grocery store. Seems to me we're in desperate need of a modern Enlightenment, this rant can be applied to many of the other issues we all love to take up on these forum boards.
